Edge and Adjacent

These two points requested to be called vertices.

Now the two vertices are isolated points of a Graph. They are not connected. A graph no needs to be connected. A graph that is not connected, of course it is called a disconnected graph.

From these two vertices, an arc line was born, and the name of the arc is an edge .

Now the two vertices are connected. The arc is connecting the two points.

Because they are connected, the two vertices are now called adjacent or neighbors .

Like a little baby, an edge cannot exist alone without at least one vertex to support it. If there is no vertex, the edge does not exist.
